Abstract: PURPOSE:To simplify an input/output to obtain a facsimile device of low price, by commonly using a writing mechanism with a reading mechanism. CONSTITUTION:When a voltage VDH is given to an electrode 1 scanning a paper, a current flowing to a paper 3 is collected with a current collecting electrode roller 2 and grounded through a contact 6 and a variable resistor 7, then a potential difference v across the variable resistor 7 is large when many current flows to the paper 3 and less when the current is less. In this state, when something is written on the paper, a voltage like (a) or (c) in Figure is generated with the scanning of the electrode. In this case, the pattern is (a) with a highly conductive writing material and (c) with highly insulating material. With discrimination levels LA and LB to be determined, when the current passes through a wave shape circuit where the level is ''1'' for larger signal than the discrimination levels and is ''0'' for smaller than them, a waveform possible for logical processing like (b) and (d) can be obtained.

Abstract: PURPOSE:To improve accuracy and efficiency of electrodepositing abrasive grains by providing an abrasive grain holding part in which the abrasive grains in plating liquid are collected in a lower side part of a plating vessel in accordance with rotating a rotary ring and, on the other hand, the abrasive grains collected in an upper side part of the plating vessel are released and enabled to drop down to a peripheral surface upper part of a grinding wheel base body. CONSTITUTION:While a current is flowed between a grinding wheel base body 16 and a positive pole 34, by respectively rotating the grinding wheel base body 16 and a rotary ring 30, abrasive grains dropped down to a lower side of a plating vessel 21 are collected by an abrasive grain holding part 32 of the rotary ring 30. Next, these abrasive grains are carried to an upper side part of the plating vessel 21, released and dropped down to an upper surface of the grinding wheel base body 16. In this way, the abrasive grains are uniformly sprayed to a peripheral furface of the grinding wheel base body associated with rotating the rotary ring, to uniformly generate a deposition condition of a metal plating phase over the total peripheral surface by rotating the grinding wheel base body. Accordingly, an abrasive grain layer of uniform abrasive grain content can be easily formed to prevent unevenness in sharpness of a electrodeposited grinding wheel due to ununiformity of abrasive grain distribution.
